Comment (by fliespl):

 I have been able to use up 512MB of memory with clean version of wordpress
 3.8.X (no plugins loaded).

 In my case post_content length was 300KB and there were about 1000
 revisions.

 I believe that this functionality shouldn't be querying full posts (since
 "metabox" only displays a list of revisions and not content) unless
 specified otherwise. Disabling post_content from this query resolved my
 memory issues. And WP was using less than 128MB.
